Perhaps you should try some spelling variations:
"historia de mathematica" » "historia de matematica", "historia de matematicas", "historia da matematica"
"historias den matematica" » "historias de matematica", "historias en matematica", "historias de matematicas", "historias del matematica", "historia del matematica"
"history e matematica" » "history de matematica", "history en matematica", "history y matematica", "history a matematica", "historia e matematica", "history of matematica"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("history e matematica") OR ((("historia de mathematica") OR ("historias den matematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history e matematica\") OR (((\"historia de mathematica\") OR (\"historias den matematica\"))))*".
• Removing quotes may allow a broader search: (( history e matematica ) OR ((( historia de mathematica ) OR ( historias den matematica ))))*.
